Be it known that I, Rox .0. Sms, of

Syracuse, in the county 'of Onondaga, lin

the State of New York, have invented newl and useful Ii'n'provementsI in Carbureters, of which the following, taken in connection with .the accompanying drawings, is a full, clear, and' exact description. a

This invention'relates to certain improvefor internal combustionengines and more particularly to 'acarbureterfor usel in connection fwith, kerosene as afuel, although it will operate eiiiciently )with other volatile fiuids.

The primary objectfof provide means for positively and .continuously drawing in, breaking up and Vaporizing a fuel, as kerosene,` independently of "the action of the piston of the engine.

to supply thefvapor- A further object is ized' fuel, under pressure, to thecylinders of the engine, whereby the cylinders are more efliciently cleansed of the spent gases and a more complete combustion takes place. .A further object is to provide a supplementary air inlet having regulating means in connection -therewith for admitting to the mixing chamber predetermined amounts' of air.

Another object is to provide a chamber below the mixing chamber and communieating therewith at ya'plurality of points, so that-the fuel willbe fed by gravity from the mixing chamber into the supplementary chamber, from which it is returned to the primary air inlet so that it will'be picked up'loy the air and carried back to the mixing chamber in a vaporized condition.

In the drawing -Figure 1 is a side elevation of the carbureter. Fig. 2 is an end elevation of the same. Fig. 3 is a cross section on line 3 3, Fig. 2. Fig. 4 is a cross section on line 4-4, Fig. 1. Fig. 5 is a cross section on line 5-5,' Fig'. 1. Fig. 6 is a cross section on line 6 6, Fig. 1. Fig. 7 is a top plan view of the supplementary air 3 inlet, showing the regulator.

` The invention comprises a mixing chamcylindrical as shown ber -1-, preferably and having near one end a tubular air inlet -2- having oneend extending below the mixing chamber and preferablv curved lin cross section,- as shown, andhaving a screen -3- at its lower end held in proper position by an internally threaded cap -4 further illustrate or describe.

invention is to which remains unvaporized,

Patented Malina-191.6.

The A'upper end-of the tubular inlet-2 Y v extends into the mixing chamber and terminates a short distance from the axis thereof. The inlet -2- is also provided with a con- \d uit -5- opening upwardlyv and leading toa loatchamber -6-'- provided with -a iioatf--- controlling a valve -`-8- in an inlet pipe -9- leading from any suitable source of supply, not necessary herein It is apparent that although I havefshown `the parts 'solfardescribed as integral, that they maybe made separately and connected in any-suitable manner, and that the conduitv 5- and the float chamber -6- may be 'separate from the cylindrical casing forming the chamber -1- and supported in any suitable manner so long as it has a discharge leading tothe .inlet -2.-.

The mixing chamber -1- is preferably formed by an elongated cylindrical body .-10- having its ends externally threaded for the reception o f caps -11- and l2- having externally threaded portions -for coaction with the externally threaded portions of the body is provided rwith a journal 1li--` respectively alined with the axis -of the cylindrical -body 10e-*for the reception of a. rotary shaft -15- having rigidly mounted thereon a pluralityl of fans -16- having their blades arranged in staggered relation so that the blades of one substantially cover up openings between the blades of the other so that it is impossible for the fuel to iiow therethrough without complete `vaporization and the blades-are so arranged that they draw the air in through the inlet -2- and the liquid from the conduit of the floatv chamber so that they are discharged in unison from the inlet -2 into substantially the center of the adjacent end of the mixing chamber -1- and are then carried lforward by the fans, positively commingled and mixed thereby and compressed in the outlet' -17- and the end yof the -10- and each of these caps l I -13- and I chamber adjacent thereto so that 'when the inlet valve of...the engine opens, the fuel rushes in and supplements the action of the piston in discharging the spent gases.

The shaft l5- Land the'fans carried thereby are positively rotated from any suitable drivingsource through the medium of mounted on the shaft. vIt

a' pulley -18- thaty a gear may be is apparent, however, used instead of the pulley -18- and likewise driven from any suitable source and e .plurality of openings -28- 1n the wall of the body -10- so that any fuel drawn in as the engine is stopping will condense and be collected in the chamber -22- and not directly in the mixing chamber, and when the engine is started vthe condensed fuel will not be thrown immediately into the cylinders of the engine, but must be drawn through the opening -23- and completely broken up and vaporized before entering the cylinders. The body -10- is also provided with a supplementary air inlet -25 at the same end of the chamber as the inlet -2- closedby a cap 2G- having openings -27- therein and a Sliding plate ,-28- pivoted to the cap -26- and likewise having openings therein adapted to be brought into or turned out of registration with the openings in the cap Q6- either fully or partially in order to regulate or entirely shut oli' the How of air from this inlet.

In operation, the positively rotated fans 16M draw the air and liquid fuel through the inlet 2-, drive it across the mixing chamber -1- and compress it in the outlet -17- and the adjacent end of the mixing chamber so that there is always a positively mixed compressed charge opening of each valve of the respective cylinders of the engine, independently of any awaiting the action of the piston and the percentages or richness of the mixture may be governed by means of the supplementary air inlet -25- and the regulating means in connection therewith.

Although I have shown a collecting chain-` ber -22- communicating with the mixing chamber for the purpose specified, it is apparent that the device will operate etliciently if said chamber is omitted, and whatever fuel is in the mixing chamber when the engine stops is allowed to condense in said chamberl and that many changes may be made in the details of construction and operation of the device without departing from the spirit of this invention as set forth in the appended claims.

WhatI claim is: l

l. A carbureter having a mixing chamber provided with a fuel inlet and a fuel outlet, a positively driven fan in said chamber, and a collecting chamber below the .mixing chamber and adapted to receive and retain the combustible fluid remaining in the mixing chamber when the fan ceases to move, in such a manner that when the fan starts this combustible Huid is drawn from the collecting chamber, vaporized and forced into the combustion chamber.

2. A carbureterhaving a mixing chamber provided with a fuel inlet and a fuel outlet, a positively driven rotary fan in said chamber, a chamber disposed below said mixing chamber, means of communication between saidl chambers whereby condensation in the mixing chamber is fed by gravity into the communicating chamber.

In witness whereof I have hereunto set my hand this 22nd day of September, 1913.
